Underground Detective Philadelphia

I had a GREAT experience with Underground detectives! From setting up with Jake and Charles arriving on time to do the gas line location. Both Jake and Charles and straight forward and very easy to work with. Thank you Underground detectives!!!

Rob and his staff are very professional and have never let us down. We've used them numerous times over the past few years and mark outs have been spot on. I highly recommend them for underground tracing needs.

We hired Underground Detective to locate the incoming water line outside our house. The fellow grounded his device to the electrical outlet in the closet where the water comes in, which I assumed would not be a problem. He had trouble locating the line, so tried two different devices, one using at least two different settings. At one point, while trying to find the water line, he actually was following the electrical wiring midway up the exterior wall of our house, seemingly due to how he grounded his device. He was not able to determine how the water line made its way to the exterior wall of our house, but did mark a path along our driveway down to the street, which should have been satisfactory for our needs. I've come to find that his marks followed the electrical wiring for the driveway lamps instead of the water line outside. After he left, I also found the power supply to my laptop dead and later found that our refrigerator wasn't cooling because the start relay had burned out. (coincidental? possibly. but both of them?) While neither of these things was good, I'd say the worst was that he sent our full credit card number in plain text in a PDF report that he email'd to me after he left. If we're not mistaken, doing so violates the business agreement with the credit card company. So we specifically would recommend against hiring these folks.
